IPC: G06F21/34
Filed: 2006-12-01
Abstract: <P>PROBLEM TO BE SOLVED: To raise the security performance of analysis data management in a system handling analysis data concerning an analyzing device or a measurement device.  <P>SOLUTION: A verification key is embedded in a key storing means in which a license key is embedded. The key storing means is established for every user, and is used as a dongle which can be carried, and (or) a predetermined data preserving area. On the other hand, analysis data, such as analysis conditions and analysis result, are beforehand locked with a lock key. If it is not confirmed that this lock key and a verification key embedded for the key storing means are associated, it prevents from using the analysis data. Since the analysis data cannot be used by other than a user who has a key storing means in which the appropriate verification key is embedded, the secrecy of the analysis data is held even if the analysis data can be revealed. By providing an authority definition part to which makes authority over analysis data to correspond about each of two or more verification keys is prepared, it is also possible to grant the authority according to a user's level.  <P>COPYRIGHT: (C)2008,JPO&INPIT

IPC: H01L21/673
Filed: 2006-12-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide a single wafer transfer tray which hardly generates dust and has a spacer having excellent stiffness.  <P>SOLUTION: A spacer 25 is formed of a core block 40 and a pair of upper and lower stack members 50, 60 mounted to upper and lower sides of the core block 40. The upper and lower stack members 50, 60 are formed of abrasion resistive materials, and the core block 40 is formed of a material having strength higher than those of the stack members 50, 60. Since the core block 40 is formed of the material having strength higher than those of the stack members 50, 60, the stiffness of the spacer 25 itself can be made sufficiently high, whereby the deformation of the spacers 25 in the stacked state or a damage involved by the deformation can be effectively prevented. Since the stack members 50, 60 mounted to the upper and lower sides of the core block 40 are formed of the abrasion resistive materials, the generation of dust caused by mutual contact between the spacers 25 in the stacked state can be suppressed and the contamination of a workpiece 4 can be avoided.  <P>COPYRIGHT: (C)2008,JPO&INPIT
